Understanding Different Bar Grating Sizes - P&R Metals
This article will provide a comprehensive guide to four common steel bar grating specifications: 15-W-4, 22-W-4, 30-W-4, and 38-W-4. If you wish to learn about 19-W-4, we have a dedicated page for it. For ADA compliance, view our page for 11-W-4.
Steel Grating Specification
Steel grating is commonly made of flat steel panel and supporting bars welded together with setting spacings. It goes through cutting, opening, edging and other processes. The popular vertical bar grating spacing is 30mm, 40mm or 60mm, horizontal bar grating is …

METAL BAR GRATING 5
current technical data on bar gratings and stair treads of steel, stainless steel, and aluminum. The information contained is based on sound engineering principles
There are three types of steel bar gratings – welded, pressure-locked, and riveted. Welded gratings are fabricated by joining bearing bars and cross bars at their intersections by welding. In pressure-locked gratings the cross bars are mechanically locked to the bearing bars by deforming the bars under tremendous hydraulic pressure.
Understanding ANSI Steel Grating Designations | Laurel
2024年12月6日 · When searching for steel grating, you’ll likely find numbers like 19W4, 11W4, and 8W4. These are all common designations for industrial and municipal steel grating. These classifications are designed to help you understand the material and configuration of the grating to ensure it meets your application’s needs.
Steel Grating Design Data Includes Thickness, Grating Bar Size
Here are the grating design nomenclature. b = thickness of rectangular bearing bar, inches. d = depth of bearing bar, inches. Aw = center to center distance between bearing bars in welded and press-locked gratings, inches. C = concentrated load at mid-span = …
These tables provide a concise reference allowing the specifying authority to select the appropriate bearing bar size and spacing for the intended application. Pedestrian loads are commonly analyzed with uniform and concentrated loads. For pedestrian comfort, deflection is typically limited to 1/4".
